Silicon-28

Silicon-28 is an isotope of silicon refined to extremely high purity levels and used in quantum computing technology. The material serves as a key building block for quantum chips, where material purity is critical for quantum system performance. Ultra-pure silicon-28 is valued in quantum computing applications because its properties support the development of stable, functional quantum devices.

China has recently announced the achievement of domestic mass production of silicon-28 enriched to high purity standards. This development represents progress toward reducing dependence on foreign sources for this critical quantum material. As quantum computing development advances globally, the production and availability of ultra-pure silicon-28 has become strategically important for nations pursuing quantum technology capabilities and supporting semiconductor supply chain independence.
